Kernel panic with pulseaudio

Having strange issue with Onion Omega2+.
Just following tutorial at https://docs.onion.io/omega2-project-book-vol1/bluetooth-audio-speaker.html (Bluetooth Speaker) and after installing necessary packages immideately getting kernel panic caused by pulseaudio process. Then I have same error on every boot and only able to restore device by doinf factory reset. Full log below.
Tried on latest firmware (b186)

Thanks for bringing this to our attention. We've investigated this on our end and have identified there is something about how ALSA interacts with the kernel DMA driver that causes the kernel panic.
We're currently looking into a solution and will keep you up to date.

@Lazar-Demin Hello, i'm trying to solve this problem too, can you explain more specifically where the root of the problem is and what modules it affects?
I debugged and find in arch/mips/mm/dma-default.c struct dma_map_ops what consist NULL, do u fix it?
